Control method for electrical appliance in hybrid vehicle

A control method for an electrical appliance in a hybrid vehicle having a motor for generating driving power for said vehicle, a generator which can control a field current and which supplies the generated driving power to said motor, and an engine for rotating said generator and driving said electrical appliance, said method comprising:

• a first step of varying the field current of said generator at the time of stopping said electrical appliance so as to increase the output of said generator by the equivalent of the output which is supplied from said engine to said electrical appliance while maintaining the revolution speed of said engine;
• a second step of gradually decreasing the revolution speed of said engine by varying the field current of said generator while comparing the output of said generator with a gradually decreasing target thereof;
• and
• a third step of operating the engine at a constant revolution speed and a constant output at the point of time where the output of said generator has reached a decreased target.

• a first step of varying the field current of said generator at the time of starting said electrical appliance so as to reduce the output of said generator by the equivalent of the output which is supplied from said engine to said electrical appliance while maintaining the revolution speed of said engine;
• an second step of gradually increasing the output of said engine while maintaining the revolution speed of said engine and comparing the output of said generator with a gradually increasing target thereof;
• and
• a third step of operating the engine at a constant revolution speed and a constant output at the point of time where the output of said generator has reached an increased target.
